ADDITIONS AND COREECTIONS TO THE LIST OP BEITISH 

 ACULEATE HYMENOPTJSBA. 



BY EDWAED SAUS"DEES, E.L.S. 



In going througli our British Aculeafces, I find a good many- 

 alterations, and a few additions, which are requisite to our list, to 

 bring it up to date, and I thought it would be convenient to collect 

 them into a short note, which could be easily referred to by Hymenop- 

 terists. The following are those chiefly worthy of notice : — 



POMPILTTS SEEICETJS, Y. d. Lind (ACTJMIlirATTJS, Smith.). 



To this must be referred the two $ specimens on which Smith based his aeu- 

 minatus ; these have long been a puzzle to me, but I have recently carefully 

 re-examined them, and have no doubt that they are very large examples of serieeus ; 

 except in size I can detect no difference between them and continental specimens. 



Salius, Fab., = Peiocnemis, Schiodte. 



Friocnemis can only be considered as a division of the very extensive genus 

 Salius, and, therefore, although all the British species belong to this sub-genus, I 

 think it is better to adopt Salius as the generic name, in conformity with continental 

 views. 



Pe. NOTATULtrs, Saund. (notatus, Saund., olim, Smith, &c., neo Eossi). 



As our species is clearly not the same as that described by Eossi, it is necessary 

 to re-name it. 



MiscoPHTJS CONCOLOE, Dahlb. (bicoloe. Smith, Saund., &c., nee Jurine). 



A careful study of Kohl's description of the species of this genus makes it clear 

 that the species which we have hitherto called hicolor is not the true hicolor of 

 Jurine, but the concolor of Dahlbom ; bicolor, Jurine, is larger than our species, 

 with the mesopleurae very densely punctured, and generally with three segments at 

 the base of the abdomen red in the ? , and two in the ^ . . 



Stigmus Solskti, Mor. (pendulus, Smith, Shuck., Saund., &c., neo Panz.). 



Here again the British species has been referred to the wrong name ; pendulus, 

 Panz., has the tubercles of the prothorax black, and the mesopleurse shining ; 

 whereas in our species the tubercles are pale, and the mesopleurse rugose on their 

 upper half. It is quite likely, however, that pendulus may occur in this country, but 

 I have not seen any specimens that could be referred to it. 



Pempheedon SntrcKAEDi, Mor., and Wesmaeli, Mor. 



In Shuckard's collection I find both these species mixed under unicolor ; they 

 appear to be quite distinct by the characters given below. As it seems to be quite 

 doubtful which of these represents the unicolor of Fabricius, or whether both are 

 included in it, I have followed Morawitz and Kohl in abandoning the Fabrician 

 name, at any rate until it can be shown what species it represents. 



Shuckardi is, I feel sure, far the commoner species of the two, as I have only 

 seen a very few specimens of Wesmaeli from Shuckard's collection, and can record no 

 exact locality for them. In ShticJcardi the puncturation of the mesonotum in both 

 sexes is sparse and shallow, the post-scutellum is shining and largely punctured, and 

 in the ? the clypeus is produced in the centre with its apex slightly elevated, the
